Deliberately unflattering light is the point. This frame's credibility comes entirely from looking like nobody set it up.
The recipe
The shot never describes the person. It describes what is happening to them, which is what keeps the face out of the variables.
Getting it right
This shot is niche-bound: the planner only puts it in a calendar for Beauty & skincare and Wellness & mind. A tape measure in a personal-finance calendar is the kind of plausible nonsense a generator produces when nobody models the constraint.
Composed
The locked line comes from the character sheet; everything after it comes from the recipe above. Swap in your own line and nothing else changes.
